4 Piston Advanced Performance RACE Valve Spring Kit (S2000)

4 Piston Racing is proud to introduce a superior valve spring at a competitive price point.  Many of the valve springs currently on the market were developed so long ago that they did not consider the RPM range and camshaft size of today's Honda performance engines. We have developed this valve spring kit with high purity large diameter wire so that you can run any of the popular camshafts on the market and operate the engine at higher RPM without the risk of valve float.  It features our nitriding treatment and Pro Polish to deliver a motorsport grade spring that will withstand rigorous endurance applications.  The retainers are a premium Titanium manufactured right here on our Mazak SYNCREX Swiss lathe to tolerances that only this type of premium equipment can achieve.  You will be happy with the packaging and presentation, and even happier with the performance and longevity.  This is the spring that you will find in our highest level endurance race engines. 100% MADE IN USA Seat Pre
